DE :
If y is a solution of given DE then it satisfied the DE.
Differentiate w.r.t t

Using the formula

LHS:
RHS

By using the formula

LHS=RHs
Hence, y is a solution of given DE

Answer:
The highest common factor is 7(3x+1)
Step-by-step explanation:
Here, we want to find the highest common factor of both expressions
As we can see, the highest common factor of 7 and 14 is 7
Now, we have the second expression which is (3x+1)
No matter what the first expression is raised to, it still stands that the highest common factor we shall have there is 3x+ 1 as concerns the term
inside the bracket
Thus, the highest common factor of both terms is 7(3x + 2)
